Unable to disable Source/Destination Check on ECS interface

[siginigin]

Hello,

I can hatch vpn server on huaweicloustack with terraform, but then I have to manually disable Source/Destination Check on interface, otherwise vpn clients can't go anywhere after connection. I did not find an option to do it neither here https://registry.terraform.io/providers/huaweicloud/huaweicloudstack/latest/docs, nor on huaweicloudstack docs to do it over API.

Can this feature be controlled only manually? Is there is an option to automate it, please kindly provide me a link how to do it.

PS: I can hide all vpn clients behind vpn server address, but that's not a way to go for me.

Thank you for help.
